25
Why even after calculation the flow rate for an IV would we check the IV hourly?
Counting drops is not precise. Rates may need to be adjusted to compensate.
26
If the patient has continuous IV therapy, how frequently should the tubing and site be changed?
The tubing for the IV should be changed every 72 hours | The site should be changed every 48-72 hours
27
TKO/KVO-
To Keep Open/ Keep Vein Open
28
How many mL of NS would you flush an IV line with
10mL
29
If IV tubing is not primed properly and air bubble can form and lead to a venous air embolism. What are some signs and symptoms for this? What are the treatments?
S & S: sudden dyspnea, tachycardia, heart murmur, hypotension, decreased LOC, CP, circulatory shock, sudden death TX: place in L lateral Trendelenburg position, 100% O2
30
What are some signs and symptoms of fluid overload?
S/S: cough, dyspnea, HTN, pulmonary edema, JVD, HA, crackles
31
When using whole blood for a blood transfusion how many mL are in one unit? What risk factors are associated with blood transfusions?
500mL/unit Risk factors include volume overload as well as passing on communicable diseases such as HEP B, HIV, West Nile Virus, etc...
32
What are PRBC's? What is their unit size? What are they typically given for?
PRBC's are packed red blood cells Unit size is 250 to 400mL/unit PRBC's are given frequently for blood loss and surgeries
33
What is the unit size of fresh frozen plasma (FFP)? What is the rate it is given?
Unit size-200-250ml given over 15-30 minutes
34
What blood product is used to treat hemophilia and Von Willebrand’s disease?
Cryoprecipitate
35
Albumin is able to increase blood pressure due to its ability to...
Draw fluids into the intravascular space
36
As an RN it is your responsibility to ensure before an IV is even started that there is an order to transfuse and that the patient has signed what?
A consent form
37
A blood product should be kept on the unit for no longer than...
30 mins. If not used by then, return the blood product to the blood bank
38
Before starting the infusion, the nurse should obtain what before administering the product?
A set of vital signs should be obtained before infusion. Make sure to obtain vital signs 5 minutes after starting the infusion as well and remain with the patient for 15 mins to ensure there are no signs of an adverse reaction. After take vitals every hour
39
What are some signs and symptoms of an acute hemolytic transfusion reaction?
S & SX: chills, fever, LBP, flushing, tachycardia, tachypnea, hypotension, vascular collapse, ARF, shock, cardiac arrest, DEATH
40
What are some signs and symptoms of an anaphylactic transfusion reaction?
S & SX: anxiety, urticaria, wheezing progressing to cyanosis, shock, cardiac arrest
41
Reactions that can occur weeks to months after blood product transfusions are called delayed transfusion reactions. Conditions and diseases that can occur with this are...
``` Delayed hemolytic Hepatitis B and C HIV Iron Overload West Nile Virus ```
42
What should be done in the case of a blood transfusion reaction?
STOP THE TRANSFUSION! Using a different IV line, KVO with NS. Notify the physicians Report to the blood bank Check ID, bag, & bag label Draw blood for a red top & lavender top tube, (which will be test for coombs) & have it sent to the blood bank with the “post Transfusion” indicated on the label. Send a urine sample to the blood bank with Post Transfusion” indicated on the label
43
Venipuncture-
inserting a hollow bore needle into the lumen of a large vein to obtain a specimen.

least traumatic, uses sterile lancet to puncture a vascular area a finger, toe, or heel
46
Arterial blood gas-
diagnosis of respiratory disorder. Arterial puncture (radial or brachial)
47

56
Hydrostatic pressure-
exerted on walls of blood vessels
57
Colloid Osmotic pressure-
exerted by protein in plasma
58
Osmosis-
area of low solute concentration to area of high solute concentration
59
Diffusion-
solutes move from area of higher concentration to one of lower concentration
60
Filtration-
movement of water, solutes occurs from area of high hydrostatic pressure to area of low hydrostatic pressure
61
Active transport-
physiologic pump that moves a substance (ions, glucose, amino acids) from area of lower concentration of one of higher concentration
62
Sodium–potassium pump-
maintains higher concentration of extracellular sodium, intracellular potassium. This pump is used in active transport
63
Osmolarity-
Describes the concentration of solutes or dissolved particles per liter (pertains to measuring fluids outside the body, ex. Urine specific gravity)
64
Osmolality-
Describes the concentration of solutes per kg of water (pertains to measuring fluids inside the body)
65
Tonicity-
The tension or effect that a solution with impermeable solutes exerts on a cell size because of water movement across a cell membrane
